The former West Ham manager is confident of at least one signing next month, but is keen to ward off any approaches for Cheikh Tiote, with Chelsea rumoured to be interested
The Magpies lost striker Andy Carroll on deadline day last January, with the player switching to Liverpool for £35 million, whilst midfielder Cheikh Tiote has been continually linked with a move to Chelsea.
"I should think [Manchester City boss Roberto] Mancini could probably say that [a player is not for sale] and possibly Manchester United manager] Alex Ferguson, but no-one else," Pardew told reporters.
"I hate the window. All managers, whether you are in the second division and you are losing a player to the first, or you have a top first division striker and you lose him to the Championship, we are all the same.
"We could lose our players to the Champions League teams, so you are all on your guard.
"Players start manoeuvring and agents - it's not a very nice period."
Defenders Fabricio Coloccini and Danny Simpson have also been linked with a move away from the north-east, and whilst Pardew refused to deny any such rumours, he did suggest that it would take a large transfer fee to prize any of his first-team squad away from the club.
"You never know with the window," he said. "It's such a minefield of possibilities.
"We have one or two players here that top clubs, I'm sure, will be interested in.
"But the one thing I would say on that is that they are going to have to pay a lot of money to take anybody out of here because we are obviously in a good position - not just on the playing side, but financially as well."
Tiote was awarded a six-and-a-half-year deal in February after an outstanding start to his career in England following a £3.5 million move in the summer from Dutch club FC Twente, and Pardew has acknowledged how integral the 25-year-old is to the Magpies.
Pardew said: "He's a big target because he's a great player, and great players are going to be targets.
"We are always on our guard with Cheik because we realise that to us, he is very, very important and it would be very, very difficult to get him out of here."
Contract negotations have stalled with right-back Simpson, yet Pardew is confident of making at least one signing next month, with Sochaux striker Modibo Maiga set to complete his long protracted move to the Sports Direct Arena.
"We will just run to the summer and see where we go then," Pardew said of the former Manchester United youngster.
"I'm not disappointed or hopeful about it - it's just business. He either does a deal here or he doesn't - and if he doesn't do a deal, we will get somebody else.
"In terms of players coming in, there is certainly one player will come in and we are hoping maybe two - if we don't lose anybody.
"I think you would be surprised - Mike and Derek are probably more keen to bring in a central defender than I am, so don't worry about that."
